"Ring" by Albert Paul appeared in the Astrocade newsletter CURSOR, 1, no. 4 (April/May 1980): 31.
Many thanks to Albert Paul of Winnipeg, Manitoba, Canada for the following program. Note: to make the ring sticker or thinner, change the value of "N" (line 2). To make the ring larger or smaller, change the value of "M" (line 20). "M" must always be larger than "N."
The BALLY BASIC and "AstroBASIC" versions of RING were typed in from the CURSOR newsletter using various program archiving tools such as PRG2TXT, TXT2PRG and KCS.
